The 2016 2. divisjon (referred to as PostNord-ligaen for sponsorship reasons) was a Norwegian football third-tier league season. The league consisted of 56 teams divided into 4 groups of 14 teams.
In February 2016 it was announced a change in format, starting in the 2017 season, that would reduce the number of groups from four to two. Therefore, the winners of the four groups were promoted to the 1. divisjon, while the bottom seven teams in each group were relegated to the 3. divisjon.
The league was played as a double round-robin tournament, where all teams played 26 matches. The first round was played on 9 April 2016, while the last round was played on 22 October 2016.[1]
